Duplicate identities collapse because the stake is slashed on collision, making sybils costly. A registration echo is broadcast to peers, and any hollow claim lacking a valid ferrous stake signature is rejected. Attackers must burn real capital per fake identity, so mass sock-puppet creation becomes economically irrational.
